Selection from DateField component that handles parsing the date string to the user's time zone

DateField time zone aware parsing

                // Regardless of the timeZone set on the DateFormat, the value is parsed in
                // the current default TimeZone. Use the calendar to adjust it out.

                Date inDefaultTimeZone = format.parse(value);

                Calendar c = Calendar.getInstance(locale);
                c.setTime(inDefaultTimeZone);

                TimeZone clientZone = timeZoneTracker.getClientTimeZone();
                TimeZone defaultZone = TimeZone.getDefault();
                long now = System.currentTimeMillis();
                int offset = defaultZone.getOffset(now) - clientZone.getOffset(now);

                c.add(Calendar.MILLISECOND, offset);

                parsedValue = c.getTime();
